Cable Cover/PVC Conduit/PVC Cable Trunking/Cable Channel//PVC Cable Duct Mode Type: ZY-T006 Charateristics of PVC ducts l        Light and convenient to transport, load and unload: PVC ducts are light. The density is 1/5 of the iron duct's, so it is convenient to transport load and unload the PVC ducts. Furthermore, the cost of installation will decrease. l        Excellent resistance to chemical substances: PVC ducts are acid-proof alkali-proof and corrosion-proof. They are suitable for the chemical industry. l        Low fluid resistance: The inner layer of the PVC duct is smooth and has low fluid resistance. Its coefficient of friction is only 0.009, which is lower than any other ducts. PVC ducts can be brought down 1-2 grades in the same flow of other ducts. l        Great mechanical strength: PVC ducts can resist the pressure of water, the outer pressure and the impact. They are suitable to piping project under different condition. l        Good insulation of electricity: PVC ducts have good insulation of electricity. They are suitable to be used as the ducts of electric wire and cable, and as the ducts of wire in the construction industry. l        No effects on the water quality: The dissolving experiment demonstrates that PVC ducts have no effect on the Water quality. PVC ducts are the best ducts as the tap-water ducts currently. l        Easy installation: Movalbe PVC ducts can be cased and joined each other. The fat-socket ducts can be joined each other with glue. It’s easy to install the PVC ducts quickly, so that to low down the installation cost.
